--- Comment #3 from Jeff Zheng <jeff.zheng at intel.com> ---
Yes this issue is still present on drm-intel-testing-2015-04-10. 

This time I used Dell U2311Hb DP monitor to workaround bug 90006. After
resuming, DP screen is black. I tried to hotplug, power off/on DP monitor, and
run "testdisplay -i", but the screen is still black. "testdisplay -a" will make
the screen recover.

I also tried S3 after X is started, the screen is black too after resuming. I
can recover the screen by running 'xrandr --output DP1 --set "Broadcast RGB"
Automatic/Full' to switch "Broadcast RGB" property.
